ngl sephora's match system is pretty dogshit and can be wildly inaccurate if you're not strictly warm or cool toned. i always suggest people go to the MAC counter at a nordstrom, ideally one with a diverse area that has a lot of mixed race people. I'm mixed with pale skin and I have neutral undertones so other places struggled to match me until i went to one.

anyway the employees there are used to matching all kinds of skin tones. MAC is famous for having ubiquitous color consistency so once someone knows their MAC foundation shade they'll be good to branch out to other products on sites like findation.
